Stockpile dust control systems are classified based on their mechanism for dust suppression and the specific requirements of the stockpile environment. Below are the primary types:
These systems use water to settle dust particles effectively.
Misting Systems:
Spray Systems:
Water Cannons:
• Use ultra-fine water droplets (micro-mist) to form a fog that captures and settles airborne dust.
• Effective in windy conditions and for fine dust particles.
• Low water consumption compared to traditional spray systems.
Utilize binding agents or stabilizers to control dust.
Dust Suppressant Chemicals:
Surface Sealing Agents:
Utilize physical barriers or equipment to minimize dust emissions.
Wind Barriers:
Walls or fences installed around the stockpile to reduce wind velocity and contain dust.
Covers or Tarpaulins:
Stockpiles are covered with industrial-grade materials to prevent dust escape.
• Combine water and chemical suppression for enhanced dust control.
• May integrate automated fogging systems with chemical sprays for efficient operation.
• Mobile units equipped with spray systems.
• Used for on-demand dust suppression on stockpiles and surrounding areas.
Incorporate sensors and programmable controls for efficient dust suppression.
Smart Foggers:
Activate based on dust particle detection or wind conditions.
Remote-Controlled Systems:
Allow operators to control spray coverage and intensity from a distance.
